After horrific shootings, we hear calls for stricter regulation of guns. The Tucson shooting should remind us why we regulate marijuana.

Jared Lee Loughner, the man held as the Tucson shooter, has been described by those who know as a "pot smoking loner."

He had two encounters with the law, one for possession of drug paraphernalia.

He goes on to argue that Loughner's affection for weed, when combined with his mental illness, worsened the situation — that things may not have been as bad had drugs been cut out of the equation.

But hey, you know what really would've made things less deadly if it had been out of the picture? Guns — the absence of guns would've made things much, much, much, much less shitty for everybody involved.
